BOTTLE-STOPPER.

SFEGIFICATION forming part of Letters Patent No. 523,474, dated July 24,1894.

Application filed January 18,1894. Serialll'o. 497,241- (No model.)

To aZZ whom it may concern.-

Be it known that I, LEWIS KALLING, of the city of Baltimore and State ofMaryland, have invented certain Improvements in Bottle- Stoppers, ofwhich the following is a specification. g

In the description of the said invention which follows, reference ismade to the accompanying drawings, forming a part hereof, and in which IFigure 1 is a sectional view of the upper end of a bottle provided withthe improved stopper. Fig. 2 is 'a top view of the stopper alone. Fig. 3is an exterior side view ofthe stopper. Fig. 4 is a view of the blankfrom which a cap forming a part of the stopper is formed.

Referring to the drawings, A is the neck of the bottle, and B the head.

The stopper consists of a cylindrical piece of cork 0 having its upperend and a part of the body inclosed by an elastic cap D. The

- cap is preferably made from a notched sheet metal blank E, shown inFig. 4, and the notches a are of such shape that when the blank isformed into a cylindrical cap, the edges 1) of the metal stand slightlyapart as shown in Fig. 3, and thereby give to the lower part of thedevice a certain compressibility. The cap is formed around the cork O,and it is provided with an annular groove 0 which in the insertion ofthe stopper in the bottle throat (1 receives an annular projection orbead e on the inner surface of the throat, and the stopper is therebyheld in place. The cap D is provided with another annular groove f nearits upper end to admit of the attachment of a suitable forked uncorkingor extracting instrument not shown. The extreme lower end of the cap, orrather the ends of the prongs formed by notching the cylindrical cap areforced inward so as to grip the cork, and thereby assist in preventingits withdrawal from the cap. The portion of the cork projecting belowthe cap is somewhat lBarger in diameter than the cap, as shown in Inclosing the bottle, the stopper is compressed in its insertion to themouth,0r until the lower portion below the groove 0 has passed over thebead e, when the stopper expands by the inherent elasticity of the cork.The tightening of the joint made by the contact of the cork with theglass, is increased as the inner surface of the cork becomes moistenedby the liquid contents of the bottle.

I claim as my invention 1. In combination with a bottle having in itsthroat a projection or bead, a stopper formed of a piece of cork and aslitted grooved cap, substantially as specified.

2. In combination with a bottle having in its throat an annular bead, astopper formed of a cylindrical piece of cork with its upper end and aportion of its body inclosed by a metallic cap having an annular grooveadapted to fit over the said bead and slits whereby the cap is madeslightly compressible in diameter, substantiallyas specified.

- 3. In combination with a bottle having in its throat an annular bead,a stopper formed of a block of cork with its upper end and a portion ofits body inclosed by a metallic cap
